Combine Solutions for Seamless Animations
Ever find yourself in a situation where you want to combine multiple datasets to create a single dataset for seamless animations and other post-processing operations? In this month’s tips and tricks video, I share a scenario that allows you to combine two separate transient studies without having to use separate editing software for video preparation. […]
Read MoreCreate Heterogeneous Materials from Images
In this month’s tips and tricks video, we are going to demonstrate how you can create heterogeneous materials using images. Click below to watch as I walk you through the process. To help you follow along, we have included the video transcription below. There’s no reason to learn software programs through trial and error, […]
Read MoreIncompressible Potential Flow with COMSOL Version 6.2
COMSOL continues to make updates to Version 6.2, and in this month’s tips and tricks video, we are going to demonstrate how you can use the new update for Incompressible Potential Flow, which can be used to replace Laplace’s Equation to initialize fluid flow equations. Click below to watch as I walk you through the […]
Read MoreSolver Improvement for Modeling of Chaotic Systems
COMSOL has made some solver improvements to Version 6.2 of repeatability in chaotic simulations, which has been helpful for a particular project we’re working on for a customer. In this month’s tips and tricks video, we share an example of how this solver improvement helps us get the same answer with the same initial input […]
Read MoreUseful Postprocessing Techniques Using the Graph Marker Tool
In this month’s Tips and Tricks video, I am going to demonstrate some useful postprocessing techniques using the “Marker” and “Graph Marker” subnodes. A very simple problem of acoustic scattering is used as an example, however, demonstrated postprocessing techniques can be used for any other physics. Click below to watch as I walk you through […]
Read MoreExporting High-Resolution Probe Data During a Parametric Sweep
Through experience, we discovered that if you want to develop an accumulated probe table, it doesn’t export the full resolution that you requested under “Updating probes.” So, in our latest Tips & Tricks video, I walk you through three steps you can take to export high-resolution probe data during a parametric sweep. Click below to […]
Read MoreHow to Develop Fly-Through Animations
Fly-through animations are a creative way to visualize inside 3-dimensional plots. In our latest Tips & Tricks video, I demonstrate how to develop these fly-through animations. The trick is, once you have your results stored in your data set, you need to define a results parameter that will be used to govern a filter of […]
Read MoreAcoustic Shock Wave: How to Speed Up Solution
With today’s technology, we have turned into a “right now” society where we have a hard time waiting for anything. As an engineer, you have probably encountered times when you wish you could speed up your simulation time. In our latest Tips & Tricks video, I demonstrate how to speed up the simulation time of […]
Read MoreUsing COMSOL Version 6.1 to Plot Non-Converged Results During Compute Attempts
As an engineer have you ever found yourself in a situation where you’re trying to track non-converged results by plotting solution variables that you would expect to behave in a certain way, but you’re not sure how to modify the initial values? In our latest Tips & Tricks video, I take you through a scenario […]
Read MoreExtending the Number of Characters Stored in the Log with COMSOL Version 6.1
In some cases, the information in the log file of a simulation is lost when the maximum number of characters in the log file is exceeded. In this video tip, we show how to increase the maximum number of characters to provide access to important data. To help you follow along, we have included the […]
